Flybridge Capital is a seed and early-stage venture firm based in Boston, Massachusetts. Founded in 2002, the firm focuses on backing founders at the earliest moments of company formation, often before product-market fit is established. It operates across technology broadly, with a thesis centered on community-led growth and founder-first partnerships. Over two decades, Flybridge has built a portfolio spanning consumer internet, enterprise software, healthcare technology, and – more recently – blockchain and crypto-adjacent companies.
The firm typically writes small checks at the pre-seed and seed stage, then follows on in subsequent rounds for its strongest performers. Flybridge does not publicly disclose its assets under management. It has raised multiple successive funds since inception. Public information on total capital raised across all vehicles remains limited; the firm has not made formal announcements about aggregate AUM.
Notable Investments
- Buzzfeed – one of the firm's earliest and most cited bets in consumer media
- ClassPass – fitness subscription marketplace, eventually acquired by Mindbody
- Kyruus – healthcare provider search and scheduling
- Flywire – global payments platform, went public on Nasdaq in 2021 (FLYW on Nasdaq)
- Tivit and other Brazil-based tech companies, reflecting selective international exposure
Flybridge's direct crypto and Web3 portfolio is smaller than its broader tech book. The firm has backed projects at the infrastructure and tooling layer rather than speculative token issuers. Specific current crypto holdings beyond what is disclosed in public databases are limited in available information. Interested parties can review the firm's disclosed portfolio on Crunchbase.
Team
The firm's most public-facing partner is Jeff Bussgang, a serial entrepreneur turned investor who co-founded Flybridge after exits in the late 1990s and early 2000s. Bussgang is also a senior lecturer at Harvard Business School and author of Entering StartUpLand. He writes regularly on venture and startup mechanics at his blog The Fundamentals. Chip Hazard is a general partner focused on enterprise and infrastructure investments. Jesse Middleton joined as a partner with a focus on community-driven companies and the creator economy. Former partners include Michael Skok and Katie Rae, who departed to lead The Engine, MIT's deep-tech venture fund.
Recent Activity
In 2024 and into 2025, Flybridge continued backing early-stage founders in AI infrastructure and developer tooling – areas that overlap with the firm's longstanding enterprise thesis. The firm has been relatively quiet in pure-play token deals, preferring equity-based exposure to crypto infrastructure over speculative asset launches. No new flagship fund announcement has been confirmed publicly as of early 2026. Public information about recent fund size and vintage is limited.
Flybridge occupies a specific niche: it competes less with mega-funds like a16z or Paradigm and more with operator-led seed firms such as Founder Collective and Homebrew. Its edge has historically been founder relationships in the Boston and New York ecosystems, combined with Bussgang's academic platform at Harvard. For crypto founders building infrastructure with an enterprise angle, the firm is a plausible early-stage partner – though its crypto deal pace is modest compared to dedicated Web3 funds.
